Editorial reviews

In Sex at Dawn, husband and wife team Christopher Ryan and Cacilda Jethá have written a book that questions both modern-day standards of human sexual behavior and the scientific history of our early ancestors. The book first explains and defines what it refers to as “the standard narrative”, the story of how humans evolved from our prehistoric ancestors to be monogamous beings with conflicting biological imperatives for males and females. Then, it goes on to refute this narrative, providing evidence from noted modern scholars like Steven Pinker, Malcolm Gladwell, and Frans De Waal, as well as renowned scientists and philosophers like Charles Darwin, Jean-Jacques Rousseau, and Thomas Hobbes.

Ryan and Jethá write, “Science all too often grovels at the feet of the dominant cultural paradigm.” Indeed, one of the most powerful ideas that Sex at Dawn puts forth is that culture has a way of coloring scientific and historical “fact”. Some of the examples given are quite disturbing, especially when large institutions are clearly engaged in cover ups of our true nature. The authors assert that many sexual myths (for example, that masturbation is some kind of medical affliction) have been repeated and disseminated over the years by religious, health, and state organizations. They take a controversial stance that this “cover up” tactic has also been applied to the non-monogamy of our closest primate relatives and early man. They believe that even if non-monogamy is not the dominant mode of being for contemporary humans, at the very least it should be viewed as a historic basis for our desires and behaviors.

The narration, which alternates between Allyson Johnson and Jonathan Davis, is clear and straightforward, particularly well-suited to this kind of book. Johnson especially makes the information, which can sometimes be dense, easily digestible and relatable. One of the authors, Christopher Ryan, reads the preface, which gives a hint of how he came to be interested in exploring the given subject matter. Through this section, we also get a way to connect directly to the authors and thus, the human (as opposed to the scientific) aspect of the issues discussed.

To claim that this work is exclusively or even mostly about sexual behavior would be a stretch. The book is very holistic, tackling bigger-picture issues of science, culture, history, and philosophy. That said, these large ideas are needed as building blocks for the claims the authors make about sex. Another triumph of Sex at Dawn is the attention the authors have given to presenting material on sex as it applies to men and women equally. Along those lines, another high point of the narration is that it echoes this sentiment through the interchanging male and female voices, reminding us that these ideas apply to both sexes in different ways.

What the book posits exactly is somewhat unclear. The authors themselves admit that they're not exactly sure what to do with all the information they have unearthed. That said, the great strength of Sex at Dawn is that it opens the discourse about human sexual behavior sans many of the taboos that traditionally accompany the topic. —Gina Pensiero

Publisher's summary

Earphones Award Winner (AudioFile Magazine)

Since Darwin's day, we've been told that sexual monogamy comes naturally to our species. Mainstream science - as well as religious and cultural institutions - has maintained that men and women evolved in families in which a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married, and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages.

How can reality be reconciled with the accepted narrative? It can't be, according to renegade thinkers Christopher Ryan and Cacilda Jetha. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book.

Ryan and Jetha's central contention is that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together convergent, frequently overlooked evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors show how far from human nature monogamy really is. Human beings everywhere and in every era have confronted the same familiar, intimate situations in surprisingly different ways. The authors expose the ancient roots of human sexuality while pointing toward a more optimistic future illuminated by our innate capacities for love, cooperation, and generosity.

BONUS AUDIO: Includes a Preface written and read by author Christopher Ryan.

Critic reviews

"A surprisingly non-titillating book about sex among prehistoric people makes for a terrific audio adaptation...With their straightforward approach, the narrators show professionalism and authority in this anthropological discussion of sex." ( AudioFile)
Sex at Dawn is the single most important book about human sexuality since Alfred Kinsey unleashed Sexual Behavior in the Human Male on the American public in 1948.” (Dan Savage)
"My favorite book of 2010...it's the only book I read this year that proved that I was badly mistaken about something." (Peter Sagal, host of NPR's Wait Wait... Don't Tell Me!)

Incredibly engaging.

The historical and statistical narratives on this book have disabused me of every assumptions about sex for the better. I wish I had read it earlier ...

This book gives a unique insight

into relationships between man and woman. Its 21st century but our sexual relations are still primal. An excellent read.

Best popular science book yet

Sex at Dawn: How We Mate, Why We Stray, and What It Means for Modern Relationships
by Christopher Ryan and Cacilda Jetha

The top review on the book's description page gives it two stars because it is "too focused on academic infighting." This isn't the case at all. The book debunks lots of unexamined assumptions, both in academia and among the general public, but it does so in an informative, entertaining, and crucially necessary way. Most people "know" that humans are "naturally" monogamous and every society has always been based on monogamy. Except they aren't, and they haven't been. So if the authors spend some time proving that what we (both the scientific researchers and ordinary people) think we know isn't true, it's far from tedious or "inside baseball" that ordinary people don't care about. It's fascinating, and well argued. I've been semi-obsessed with human evolution for the past few years, and the authors have explained who we are and how we've become this way more in this one book than practically all the rest I've read put together. I wish they'd get busy and write a lot more books! :-)

This book makes more sense of the mountains of evidence right in front of our eyes about human sexuality and why we feel and act the ways we do about it than anything I've encountered. And it's delivered in very accessible style, with wit, insight, and wisdom. The readers of the audio book do a terrific job as well. (Jonathan Davis reads the epigraphs etc, and Allyson Johnson handles the narration with great skill.) I can't recommend this book highly enough; it's the best I've read in years on this or any other subject.

interesting

eye opening, a challenge to conventional thinking. A healthy thoughtful critique of the current modern narrative with its underlying shame message attached to sexuality. Giving thought provoking dialogue to allow people to challenge and let go of the shame and guilt placed upon us by the construct of modern day interpretations of something perfectly natural an healthy.

Super interesting to hear the options that we can have in intimacy and relationships

I really enjoyed this book I found it super informative and cheeky in its presentation. I thought it was so helpful in dismantling handed down ideology that I always felt didn’t fit me!

Must read for every human being!

This book should be MANDATORY for all college degrees or the terminal year of high school. It would benefit every human being on the planet to understand and reflect upon the knowledge and ideas presented in this book concerning the anthropology and biology of sex and human relationships.
